  • The purpose of this study was to develop the standardized manual for dietetic internship. The general information of the dietetic internship program in Korea was gathered and of dietetic internship(DI) in the USA was also surveyed. The existence of DI program manual, the number of intern and length of the dietetic internship program, and other general information were investigated. At first, the questionnaire was developed and mailed to 130 hospitals in Korea and the number of returned questionnaires was 42 showing participating rate of 28%. Second, telephone survey was carried out and the number of response was 40 out of 46 participating rate of 87%. The results of this study could be summarized as follow. 1. eneral informations of dietetic internship program in Korea; The hospital having a dietetic internship program was 31.7% and of them 14.6%(12 hospitals) have a manual developed by themselves. The number of dietetic intern per hospital was 2.0$\pm$ 1.4. The length of the program was from 3 to 12 months. Ten hospitals (38.5%) have a only food service program and 16 hospitals (62.5%) have both food service and clinical program. Seventy one percent (58 hospitals) of total hospital were willing to use the well developed standardized dietetic internship manual. 2. eneral information of Dietetic Internship Program in the USA; Two hundred fifty nine hospital had the dietetic internship program approved by ADA. The number of dietetic intern in each hospital was 10.6$\pm$ 6.3. The mean length of the program was 13.6$\pm$ 6.3 months. Twenty seven percent of institution have coordinated internship/masters degree program. The range of tuition for DI program was from 300 to 30,855(otherwise, interns were payed by the hospital in Korea). As a conclusion, the standardized dietetic internship program for the clinical dietitian as nutrition professionals to carry out their job at the hospitals should be developed. And the coordinated internship/masters degree program could be considered to improve the skill levels and job performances of clinical dietitian.

  • In order to obtain the fundamental informations on cellulase of Trichoderma viride QM 9414 for its production and utilization, some physico-chemical properties of the enzyme were reviewed. When T. viride QM 9414 was cultured on wheat bran medium, filter paper-disintegrating and carboxymethyl cellulose-saccharifying activity were increased with the cell growth, and thereafter CMC-saccharifying activity was kept on almost the same leved while filter-paper disintegrating activity was decreased sharply. And B-glucosidase was formed maximally on the late stationary phase of growth. The crude cellulase of cell-free extracts was purified by (NH4)2SO4 fractionation, Sephadex-G 200 column chromatography and DEAE Sephadex A-50 column chromatography. Filter paper-disintegrating, CMC-saccharifying and B-glucosidase activity were purified 10-fold, 47-fold and 38-fold, respectively. The crude enzyme was proved to be a complex of three different enzyme proteins which were showing filter paper-disintegrating, CMC-saccharifying and B-glucosidase activity. The optimal pH of the three enzyme components was alike pH 4.0, and the optimal temperature for CMC-saccharifying, filter paper-disintegrating and B-glucosidase activity were 4$0^{\circ}C$, 45$^{\circ}C$ and 5$0^{\circ}C$ respectively. The Km and Vmax values of CMC saccharifying activity for CMC were 0.485% and 3.10, and the Km and Vmax vallues of B-glucosidase for PNPG were 0.944$\times$10-3M and 0.097, respectively. The Km and Vmax values of filter paper-disintegrating activity for Avicel were determined to be 0.09% and 0.178, respectively. B-Glucosidase activity was competitively inhibited by glucose, and the Ki value for this enzyme was 3.54$\times$10-3M, CMC saccharifying activity was found to be greatly inhibited by cellobiose.

  • This study is to investigate the trend of researches on food and culture from 1990 to 2003. With a literary approach, this paper analyzes how many papers were published and what was the major research subject. We classified the journals published during this time into 10 different categories and we are to grasp a research trend. 1) Historical approach on the traditional food and food habit; 2) Globalization of Koran food; 3) Use and preparation for traditional food; 4) Table setting and table manner; 5) Provincial cuisine; 6) Traditional festive food or celebratory meal; 7) Religious food; 8) Fusion food; 9) Food and culture in foreign countries and food habit of Korean people living abroad; 10) Studies related with satins out. It was revealed that 268 papers(=ps) were published. Eating out was the most frequently reported subject(100 ps), followed by provincial cuisine(54 ps), use and preparation for traditional food(49 ps), food habit for foreign people and Korean people living abroad(22 ps). Researches on these 4 topics have been accelerated since the late half of 1990s. This reflects the social factors such as rapid growth of food service industry, settlement of local autonomy, popularization of leisure activities and accelerated introduction of foreign food and culture. Half of the studies on the eating out dealt with eating out behavior. And 30 papers were reports on the food service industry situations. More than half of the studies on the provincial cuisine(26 ps) were concentrated on digging out recipes. Studies on the use and preparation for traditional food were mainly about what kind of food and how often the food is used(17 ps). Kimchi was the most frequently studied food. There were 11 papers regarding food and culture in foreign countries. Most of the authors were historians or linguists. Food habit of Korean people living abroad were investigated in 7 papers. There was few studies on fusion food, table setting and table manner. This doesn't meet with increasing demand for specialized information in then fields. Researches on the traditional festive food or celebratory meal(5 ps) and religious food(9 ps) were negligible. Papers on the historical approach to the traditional food and food habit were limited(12 ps). Moreover, most of them were patchwork of existing literatures. Continuous researches to exploit the historical facts based on literary proof should be tried with patience. Otherwise, the papers will copy the hackneyed knowledge repeatedly. Globalization of Korean food means the development of Korean food for foreign people and export of them worldwide. Only 16 papers were reported on this subject, 14 of them were published after 2000, 8 of them were surveys on the foreigners' food preference. In order to get practical informations on what we develope and how we sell for the foreign customers, profound research on their food habit should be done.

  • This study was conducted to investigate the nutritional knowledge, nutrients intake and the assessment of dietary behavior of old peoples living in Incheon area. Two hundred and three elderly were examined using the questionnaire. The results of this study are summarized as follows. 1. The old people was lacking in correct information about nutrition and diseases. 2. The nutritional knowledge scores of old women were higher than those of old men and the scores went up according to the amount of pocket money. 3. The amount of vitamin C and phosphorus intakes were higher than those of the RDA, protein intake reached the level of the RDA. The vitamin B$_2$intake, however, was below 75% of the RDA and that of calcium was very low in women, especially. 4. Most of subjects had a meal regularly three times a day and the skipping rate of breakfast was very low. Dey had a moderate meal volume and did not have an unbalanced diet. Dey nearly do not take the processed food, dine out and exceed in the cholesterol intake. 5. They took green and yellow vegetables and, milk and milk products relatively small. On the other hand, the intake of caffein beverage was relatively high. the rates of drinking and smoking were low. From these results, we may propose the conclusion as follows: The old people were much concerned about the nutrition and diseases, but they had no correct informations about them. Therefore, the program of nutrition and dietary behavior for their healthy elderly life had to be prepared and to be applied to them immediately.

  • This paper is intended to study what kinds of the vegetables are mentioned in the Bible and how they were used in those days. While one hundred and twenty-eight different plants are mentioned in the Bible, there are today 2,384 plant species in modem Israel, most of which have been introduced in recent centuries. These plants obviously did not exist there in biblical times and were only recently introduced from Australia and South America, respectively. This article will study only the vegetables mentioned in the Bible and known to have existed in the old and new testament times. Since the first book devoted exclusively to biblical botany was that of Levinus Lemmens in 1566, the modem systematic study of biblical plants, began with F. Hasselquist, a student of Linnaeus, the founder of modem botany. In 1928, Immanuel Loew approached the subject differently, reviewing all known data pertaining to biblical plants. His work not only discussed biblical plants, but also plants in later Jewish literature, particularly the Talmud. The British scholar G. E. Post provided a broad field study of modem plants in Palestine, Syria, Lebanon, and Jordan. More recent major treatments of the subject include those of A. and H. Moldenke (1952), M. Zohary (1982), N. Hareuveni (1984), and Y. J. Choi(1996). Today, articles on specific biblical plants listed in the Bible can be found in any number of encyclopedias. This study attempts to provide a synthesis of the work of a number of scholars who studied the vegetables and plants mentioned in the Bible. As a preliminary study on the culture of food in the biblical period, this study has focused on the identity and features of the vegetables of the Bible. In only a limited number of instances, because of the paucity of the informations and the broad and generic descriptions of the plants, we can't be certain about the identification of the vegetables named in the Bible. In many instances the traditions established by the Greek, Aramaic, and English translations are helpful, although sometimes they are misleading. This paper subdivides the vegetables into broad areas, the general vegetables and the flavoring herbs. Vegetables formed very important part of the diet in the biblical times. Two main types were used: those whose nutritious seeds could be easily stored and those which were eaten freshly gathered from gardens. Pulse seeds provided a useful source of vegetable protein, while fresh green vegetables were vitamin rich. Pulses could be eaten boiled, or their dried seeds could be ground up into flour and then made into nutritious soups. Fresh vegetables were eaten either raw or lightly cooked, usually by boiling in water. The general vegetables in the Bible are herbs(garden rocket), cucumber(snake cucumber), watermelon, leeks, chicory, and onions. Also the flavoring herbs in the Bible are rue, dill, cummin, black cummin, frankincense, cinnamon, cassia, myrrh, black mustard, coriander, mint, saffron, ginger grass, syrian hyssop, aloes(eagle wood), manna which have the flavor, aroma, and medical values.

  • This study was conducted to investigate the mothers' nutritional knowledge on weaning of 101 infants (8 for 4 mo, 44 for 5 mo, 45 for 6 mo, 4 for 7 mo) at a public health center of Incheon. Informations on the mothers' nutritional knowledge were obtained by questionnaires. In this survey $41.6\%$ of infants were breast-feeding, $43.6\%$ of them were bottle-feeding, and $14.9\%$ of them were mixed feeding right after birth. The rate of breast-feeding right after birth was significantly higher in mothers of high school graduate than mothers of college/university graduate (p < 0.05). The infants of mothers graduated high school began to be weaned significantly earlier than the infants of mothers graduated college/university (p < 0.05). $95.1\%$ of infants (n = 101) began to be weaned 4 to 6 months. $83.1\%$ of infants were fed home-made weaning foods. $66.7\%$ of infants were fed rice gruel, $18.5\%$ of them were fruit juice, $6.2\%$ of them were mixed grain, and $4.9\%$ of them were commercially prepared weaning foods as their first supplementary foods. As main supplementary foods, $32.8\%$ of infants were fed vegetable, $30.5\%$ of them were rice gruel, and $27.7\%$ of them were fruit juice. Mothers' nutritional knowledge related to weaning was significantly higher among mothers of college/ university graduate than mothers of high school graduate (p < 0.05). $86.1\%$ of mothers disagreed with the questionnaire in which breast-fed infants aged over 4 months needed to be fed iron sufficient food. For the improvement of nutritional status especially iron nutritional status of infants, nutritional education for mothers with weaning aged infants has to be increased and related programs have to be operated effectively.

  • The objectives of this study were to assess the current practices of implementing selective menus and to identify the perception of foodservice manager and customer on selective menus for hospital foodservice would be fulfilled. Two types of questionnaires for hospital foodservice managers as well as customers were developed. Questionnaires were distributed to managers of 8 hospital foodservice department and 317 customers of patient meal service, and 6 managers and 139 customers were responded. The data were analyzed using frequency and t-test. The results of this study can be summarized as follows : 1. In hospital foodservice operations, the selective menu pattern was first introduced by L hospital on June 1994 in Seoul and recently 8 hospitals were currently implementing selective menus. But using rate of selective menus by patients were relatively low(23.2%), ranging from 15% to 32%. 2. Customers' needs for selective menus were rated significantly higher in the group of patients(4.24/5) who chose the selective menus than their counterpart(3.88/5). 3. The main reason not choosing selective menus was identified by patients as 'not knowing the implementation of selective menus'(52.6%), inconvenient factors in using selective menus for customer were also identified as orders : 'lack of nutrition information on menu item'(38.6%), 'complexity in procedure'(29.8%), and 'lack of menu variety'(26.3%). However managers considered 'managerial burden' and 'limited human resource' as main obstacle to implement the selective menu pattern. 4. Customers indicated 'variety of menu', 'active public relations' as effective methods to enhance using rate of selective menus, however, foodservice manager indicated 'variety of menu'(50%), 'improvement of quality'(16.7%), and 'simplicity in procedure'(16.7%). Based on the results of this study, following recommendations have been suggested : Managers in patient meal service should recognize customer needs for implementing selective menus and pay more attention in implementing selective menus and activating this program. For more effective implementation of activating selective menu program, the foodservice department should establish action plan on 'active publicity work', 'simplicity in procedures', 'variety of menu' and 'improvement of quality'. Especially nutrition informations on meals should be provided for customers in order to elevate participation rate.
